MySQL查询间隔8个月后获取记录

为此，请使用INTERVAL8MONTH并从当前日期开始获取8个月的记录-

select *from yourTableName where yourColumnName>= (CURRENT_DATE() - INTERVAL 8 MONTH);

注意-假设当前日期是：2018-02-06

让我们首先创建一个表-

mysql> create table DemoTable (StudentName varchar(100), AdmissionDate date);

使用插入命令在表中插入一些记录-

mysql> insert into DemoTable values('John','2019-01-21');
mysql> insert into DemoTable values('Chris','2019-10-04');
mysql> insert into DemoTable values('Robert','2018-02-01');
mysql> insert into DemoTable values('David','2019-07-07');

使用select语句显示表中的所有记录-

mysql> select *from DemoTable;

这将产生以下输出-

+-------------+---------------+
| StudentName | AdmissionDate |
+-------------+---------------+
| John        | 2019-01-21    |
| Chris       | 2019-10-04    |
| Robert      | 2018-02-01    |
| David       | 2019-07-07    |
+-------------+---------------+
4 rows in set (0.00 sec)

以下是间隔8个月后获取记录的查询-

mysql> select *from DemoTable where AdmissionDate >= (CURRENT_DATE() - INTERVAL 8 MONTH);

这将产生以下输出-

+-------------+---------------+
| StudentName | AdmissionDate |
+-------------+---------------+
| John        | 2019-01-21    |
| Chris       | 2019-10-04    |
| David       | 2019-07-07    |
+-------------+---------------+
3 rows in set (0.00 sec)
